I have an ebookwise (ebookwise.com and about $160) reader and I love it. Right size, lights up, holds charge. The thing I don’t love about it is that too many of the NY bestsellers and new books don’t offer the secure format that works on mine (secure .imp). I can get all my small publishing house books on it (but not adobe format), and a large number of NY titles…but not all.
However, they are working on a standard format for ebooks so all ereaders can access them. That will make me happy.
The reason I didn’t get a kindle, aside from price, was beacause it doesn’t have a backlight and I specifically wanted to read in bed. I have occasional insomnia and my husband does not.
